W/ 771 53 S56: 0 1y INVENTOR 6 0 FfiAm/ra/mM/ELL By k ff ATTORNEY :Origlnal application filed November FRANK B. HOWELL, or BUFFALO, new roan, nssrenon T nnnnrcnniaanrn'ren COMPANY, or cnroneo, I LINOIS, A eonronarron or NEWJEEYJ HEATING emanates.-

To all'whom it may concern;

Be it known that-I, FRANK-JP). HQWELLL a citizen of-the United States, residing at If the city of Buffalo, Erie county, in the State v of New York, have invented certain new and usefullmprovements in Heating Apclear, and exact specification My invention relates to improvements in heating apparatus, and the same has for. its object more particularly to provide a simple, efficient and reliable stove in which the fuel receptacle 0r fire box is constructed and arranged to maintain the fuel in the form" of a relatively thin or narrow vertical-column through which the draft is passed cross wise or horizontally.

Further, said invention has for its object .itae'le w ich occupies one side of the stove,

to provide a stove having a fire box or fuel receptacle, combustion'chamber and its draft passages and appurtenances so, constructed and arranged to permit of the burning of all kinds of fuel lessly.

Further, said invention has for its object to provide a stove havin a fire box or fuel receptacle in which the air necessary to support combustion is not permitted to-enter the fire boxor fuel receptacle directly but is conducted --longitudinally thereof through heated flues arranged at one side of thereceptacle, and at the back thereof, inorder to preheat the air, and thence conducted to the opposite side of the receptacle whereit is delivered to the interior of thefirei'box or fuel receptacle in a series of superposed, parallel, horizontal streams or jets.

Other objects will in art be obvious and in part be pointed out ereinafter.

To the attainment of the aforesaid objects and ends my invention consists in the novel details of construction, and in the combination, connection and arrangement of parts hereinafter more fully described and then pointed out in the claims.

In this application I do not claim 'the general construction of the stove as a2whole, as the same forms the subject matterjof another application filed by-me on November 14, 1914;, Serial No. 872,122, of which this application-fie a division. II1 the'pres-- ent application, therefore, I have shown, described and claimed the fire box or fuel I receptacle apart from the stove generally.

form of range or stove provided with a fire box or fuel receptacle constructed according paratus, of which thefollowing is a full,

the line 3-3 of Fig. 5;

Fig. 4: is a vertical section at right angles to .F1g. 3, and taken on the line t-t of Fig? 6;

Fig 5 is a vertical section taken onthe Fig 6 is a horizontal section taken on the 10 re resents the fire box or fuel recepas shown in the drawings the left handside when viewed from the front. Positioned above" the fuel receptacle is the combustion .the stove, and 12 represents the water heater vwhich occuples the portion underneath the oven, which is the lower right hand por "tion, as shown in the drawings.

f re

13 represents the top plate which extends over; the combustion chamber and the oven and isproVided with a suitable number of openings for cooking vessels. The openings areprovided-with the usual covers 14. The

-. exit opening 15 for connection with the stove pipeis arranged in this top plate in rear ofjthe oven.

' The fuel receptacle 19 is high and narrow order to'hold the fuel in the form of a ,tall columnwhich is narrow in the direction in-which' the draft passesthrough the fuel and has its draft passages so arranged that the draft passes transversely through the column of fuel from onefside'to the other. In the construction shown in the drawings, the draft-passes through the fuel receptacle transversely from-the side thereof which is adjacent to: the end of the stove toward the side thereof at which the oven and the water heater are arranged. I r

. The air for the support of combustion enters: an upright air chamber 16 which forms the narrow front wall of the fuel are ceptacleand which is provided in its front plate with a vertical series of air inlet openings 17. Air inlet passages 18 extend inline with these openings through the insulated or lined outer wall 19 of the stove, Fig. 6. The inlet openings 17 are controlled by a vertically adjustable register plate 20, Figs.

1, 3, 5 and 6, having openings 21 eorrebars 23, the cavities of which form air passages communicating at their front or inlet ends with the front air chamber 16 and at their outlet ends with an upright air chamber 24 forming the narrow rear wall of the fuel receptacle. These hollow bars extend lengthwise from the front air chamber 16 to the rear air chamber24 and are separated by draft exit passages 25' through which the flame and hot gases escape from the fuel receptacle. The upper and lower sides of these hollow bars are inclined so as to rise in the direction of the draft and awayfrom the column of fuel in order to confine the latter within the fuel receptacle. This upright series of hollow bars connects the front and rear air chambers and forms an upright grate between these chambers on the exit side of the fuel receptacle.

26 represents spaced bars which constitute an upright grate on the inlet draft side of the fuel receptacle and extend from the rear to the front air chamber of the same. These bars are inclined like the hollow bars 23 but are solid and are separated by air pas sages 27 intowhich the air is delivered from the rear air chamber 24 through openings 28 in the adjacent plate of the rear air chamber, Figs. 4 and 6. These solid'bars 26 are preferably provided on their under sides along their edges with longitudinal ribs 29, 30, Fig. 4, to better confine the air currents, which ribs give these bars an in verted channel form.

In the operation of this fuel receptacle the air for the support of combustion enters the front air chamber 16, passes through the hollow bars 23 of the exit grate, then through the rear air chamber 24, and then through the spaces between the solid bars 26 of the indraft grate and enters the fuel receptacle through the passages 27 between the bars 26. These chambers and bars are constructed of cast iron or other suitable the front air chamber, the hollow bars of the exit grate, and the rear air chamber becomes highly heated and issues' into the column of fuel at the indraft side of the fuel re ceptacle in a highly heated state, whereby the complete combustion of the fuel is promoted and the formation of smoke is practically avoided.

31 represents supplemental air inlet openings formed in the end wall 32of the stove at the indraft side of the fuel receptacle and in line with one or more of the air passages between the indraft bars 26. These openings are controlled in any suitable manner, for instance, by pivoted covers 33, and may be employed if the nature of the fuel requires an additional air-supply to the fuel receptacle.

34,.Figs. 4, 5 and 6, represents an upright main flue. which is arranged on the exit side of the fuel receptacle. The exit draftpassages'25 between the, hollow bars 23- open into this flue from which the draft is directed in various ways through branch flues, as the user may desire. The upper portion of this main fiueextends across the indraft side of the oven which is separated from this flue by an upright partition or plate 35 extending from the top plate of the oven to the bottom plate thereof and from the front wall to the rear wall of the stove. Above this upright partition and underneath the top plate of the stove there is arranged a damper 36 which controls the passage leading from the upper'end of this flue toa horizontal flue 37 which is arranged between the top of the oven and the top plate of the stove and which communicates with the exit opening 15 with which. the stove pipe is connected. Upon opening this damper, as shown in Fig. 4, the draft passes directly from the upper end ofthe upright main flue to the exit opening 15, and the heat is practically concentrated upon the top plate of the stove andcut off from the oven and from the water heater. .By closing this damper, as shown in F ig. 5, the draft is prevented from exit opening 15.

38 represents a. horizontal lcafile plate arranged underneath the oven andabove the water heater, and separated from the bottom of the oven by a horizontal intermediate flue 39 which communicates at the rear. side ofthe stove with an upright flue extending upwardly on the rearside' of -the oven to the horizontal top flue 37.. The lower porpassing directly to the tion of the upright main flue 34 is arranged adjacent to the water hea'ter'from which it is separated by an upright partition or plate 41 which extends from the horizontal baffle plate 38 downwardly and is separated at its lower end from the bottom of the stove by a;draft' passage 42. The horizontal baffle plate 38 is provided near the main flue 34 with draft passages 43. The passage lead ing from the main flue to the horizontal flue 39 beneath the bottom of the oven is controlled by a damper 44. Upon closing the latter and the top damper 36 the draft is directeddownwardly through the main flue and through the bottom passage 42 to the lower portion of the space in which the water heater is arranged. The draft passes upwardly through this space, supplying heat to the water heater, and passes through the passages 43 in the horizontal baffle plate 38 into the horizontal flue 3.) and thence through the upright rear flue 40 to the exit opening 15 to which the stove pipe is connected.

Upon closing the upper damper 36 and opening the lower damper 44the draft is directed'from the main flue 34 to the horizontal flue beneath the oven and cut off from the water heater. In this position of the dampers the heat is utilized mainly for heating the top plate and the oven, as in cooking and baking, and but little heat is supplied to the water heater.

The water heater shown in the drawings is composed of several connected sections, or chambers and provided with a flow pi e 45 and a return pipe 46. It may also be provided with a faucet 47 for drawing ofl" hot water. The particular construction of the water heater is unimportant and any suitable construction may be employed.

48 represents the grate, 49 the ash pit, 50

the ash pit door, 51 the oven door, and 52 the door leading to the space in which the water heater is arranged. l
